“This is an easy one. I like Stio’s Basis Power Wool. Next to skin it features merino wool’s superior odor and moisture wicking, while the exterior of the garments is synthetic poly, which is more durable and breathable. You don’t get the pilling, running, or tearing of a wool base layer, and you don’t get the stinkiness of a pure poly/spandex base layer. I’ve been wearing them almost every day here in Jackson Hole skiing, fatbiking, and winter running, no problem.” —Frederick Reimars, freelance outdoor writer and former editor at Canoe and Kayak Magazine
“Long underwear made with merino, nature’s finest performance fabric, is the best because it stays dry to the touch as it pulls moisture away from you, leading to a way nicer body climate. I like the Patagonia, but those are nearly sold out, so I like the Icebreaker too.” —Abe Burmeister, founder, Outlier clothing
